Specification of Letters Patent.

Patented Apr. 15, 1919.

Application iled November 27, 1917. Serial No. 204,254.

To all whom 'it may concern Be it known that I, Flinn S. CARR, a citizen of the United States, and a resident of Newton, in the county of Middlesex, Coinmonwealth of Massachusetts, (whose postoflice address is care of Carr Fastener Company, Cambridge, Massachusetta) have invented an Improvement in Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to stud and socket fasteners.

Among the objects of the invention are to provide a socket having resilient jaw means for engagement with the neck of the stud which is simple in construction, reliable in operation, and in which the entrance of the stud into the socket -is very easily effected, while retaining those advantages which are inherent to stud and socket fasteners wherein separation of stud and socket can be effected by relative tipping movement in one direction only.

In the drawings:

Figure l s a `front elevation showing a preferred form of one embodiment of my invention;

Fig. 2 is a section thereof, partly in elevati-on, on the line 2-2 of Fig. 1;

Fig. 3 is a sectional view, partly in elevaton, on the line 3 3 of Fig. 2; and

Fig. 4 is a section, partly in elevation, on the line 4 4 of Fig. 3.

Referring to the preferred form of my invention selected for illustrative purposes, I have shown a stud 5 having a head 6 and providing a neck 7 for engagement by resilient jaw means typified by the transverse resilient jaws 8 and 9 carried in a socket which preferably, as shown, comprises a front casing 10, and a rear casing 11. The stud 5 may be secured to the curtain 12 of an automobile, or any other suitable object, while the socket may be secured to a second curtain 13, or any other suitable object, preferably a fabric, preferably by pronos 14 projecting from the front plate 10 ofD the casing and passing through a clench plate 15.

One of the resllient jaws, preferably the lower jaw 9, is preferably free to move in either direction toward or from the aperture 16 in the socket. The other resilient jaw, herein shown as the upper jaw 8, is

preferably supported on one side by an inclined surface 17, which may conveniently be formed in the back plate 11 and which is adapted to oppose movement of the jaw 8 away from the axis of the aperture 16 when the stud is to be withdrawn from the socket, but which is relatively free to move away from said axis when the stud is to be entered in the socket. I preferably space the front plate 10 (Fig. 4) at a` sufficient distance from the back plate 1l so that when the spring jaw 8 is pressed forwardly, as is necessarily the case when the stud is entered in the socket, the spring jaw 8 will be moved away from the cam surface 17 and therefore be free to move upwardly, thereby yielding to facilitate entrance of the head of the stud in the socket. When, on the other hand, the stud is to be withdrawn from the socket, the front shoulder of the neck or groove 7 presses the jaw 8 firmly against the back plate, in which position the jaw 8 will not move upwardly because of the inclined projection 17.

When the stud is to be removed from the socket, the lower end of the socket may be moved outwardly, which will cause the lower jaw 9 to yield downwardly so that the stud can be rocked about the jaw 8 to permit withdrawal of the stud from the socket by an unbuttoning action.

While I have shown and described one embodiment of my invention, it will be understood that changes involving omission, alter-ation, substitution and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.

Claims:

1. A stud and socket fastener comprising, in combination, a stud having a head and a neck, a socket providing a jaw element yieldable when said stud is entered in the socket but substantially unyielding when said stud is withdrawn from said socket.

2. A stud and socket fastener comprising, in combination, a stud having a head and a neck, a socket providing a resilient jaw and a stop element coperatin with said 311W to oppose movement thereo on retraction of said stud from said socket, while permitting said jaw to yield substantially freely when said stud is entered in said socket.

3. A stud and socket fastener comprising,

in combination, a stud having a head and a neck, a socket providing a transverse jaw element yieldable when said stud is entered in the socket but substantially unyielding when said stud is withdrawn from said socket.

4. A stud and socket fastener comprising, in combination, a stud having a head and a neck, a socket providing a transverse re silient jaw and a stop element coperating with said jaw to oppose movement thereof on retraction of said stud from said socket, while permitting said jaw to yield substantially freely when said stud is entered in said socket.

5. A stud and socket fastener comprising, in combination, a stud providing a head and a neck, a socket providing transverse jaws for engagement with opposite sides of said neck, one of said jaws being freely movable away from said neck, and the other of said jaws having an abutment opposing movement of the latter jaw away from said neck.

6. A stud and socket fastener comprising, in combination, a stud providing a head and a neck, a socket providing transverse jaws for engagement with o posite sides of said neck, one of said jaws ein freely movable away from said neck, and t e other of said jaws having an abutment o posing movement of the latter jaw away rom said neck when said stud is withdrawn from said socket.

7. A stud and socket fastener comprising, in combination, a stud providing a head and a neck, a socket providing transverse jaws for engagement with opposite sides of said neck, one of said jaws being freely movable away from said neck, and the other of said jaws having an abutment opposing moves ment of the latter jaw away from said neck when said stud is withdrawn from said socket, while permitting substantially free movement of said jaw away from said neck when said stud is entered in said socket.

8. A stud and socket fastener comprising, in combination, a stud having a head and a neck, a casing having resilient jaw elements therein for engagement with said neck, said casing having an inclined portion at the rear thereof coperating with one of said jaws to oppose movement thereof when the stud is withdrawn from the socket, while permitting movement of said jaws when the stud is entered in the socket.

9. A stud and socket fastener comprising, in combination, a stud having a head and neck providin between them a shoulder; a socket providing a jaw element yieldable when said stud is entered in the socket but substantially unyieldable when said stud is withdrawn from the socket, and providing a second jaw opposite the first jaw, said second jaw being yieldable when the stud is entered in the socket and when disengaging force is applied to the stud and socket to produce relative tippin movement about the first named jaw as a fu crum.

In testimony whereof, I have signed my name to this specification. t
